I am looking for an efficient way to display events listed on 15-25 child sites into one main parent site for a client. One plugin that does this very effectively is the [Events Calendar Pro – Event Aggregator](https://theeventscalendar.com/products/event-aggregator/), but they have a **10 site limit** to pull the events from.Does anyone know of a way I could achieve something similar to this, but can be used for more than 10 sites?
